Why it moves the price
The stock stops trading on fundamentals and starts trading on the deal price, discounted for the risk the deal breaks.
What separates a good call from a naive one
The largest single-day moves in equities, but the upside is capped at the bid — buying after the pop offers small returns for real deal-break risk. The gap between market price and offer price tells you what the market thinks of the antitrust odds.
